| Abstract: | The complicated geological conditions have been restricting the exploration and development of deep natural gas in West Sichuan Depression.Through analyzing the main geological problems in the drilling process of the area and the difficulty and characteristics of drilling fluid technology,such as wellbore instability,lost circulation,well kick and drill pipe sticking,we put forward the technical measures for the optimization of rheological behavior of drilling fluid with high temperature and high pressure and borehole stability.They can be used for the guiding of drilling design and field operation,which decreases the incidence rate of complex incident and implements the destination of the drilling with high quality,safety,high efficiency and low cost in order to accelerate the pace of petroleum exploration. |
| Keywords: | underground complex borehole instability abnormal pressure security density drilling fluid technological measure West Sichuan |
